venkata ram kumar ch updated HDFS-14117:
----------------------------------------
Description:
When we delete files or dirs in hdfs, it will move the deleted files or dirs to
trash by default.
But in the global path we can only mount one trash dir /user. So we mount trash
dir /user of the subcluster ns1 to the global path /user. Then we can delete
files or dirs of ns1, but when we delete the files or dirs of another
subcluser, such as hacluster, it will be failed.
